My students in evidence design at Yale over the years have also made sunspot
movies, scanning the original engravings from Galileo's Istoria e dimostrazioni
intorno alle macchie solari (Rome, 1613). I show one of those student movies
in my one-day course.

Good modern-day sunspot movies, which show recent exciting sunspots, are posted at SpaceWeather.com

I can't help but contribute this stunning animation of the sun in rotation over a six day span. Having just participated in Tufte's course in New York, compared to Galileo's sunspot movie, this animated gif is particularly interesting.

Other stunning photos of the sun, including close up images of actual sunspots, can be found on the Big Picture blog
